An unusual 2, 12-connected 3-D open framework based on {As2Mo6O26}-type polyoxometallate and copper-pyrazole complex

An unusual 2, 12-connected 3-D open framework with a new {26·448·612}{2}6 topology based on {As2Mo6O26}-type polyoxometallate and {Cu(pry)2} complexes has been hydrothermally synthesized. Compound 1 exhibits good fluorescent properties in solid state at room temperature and bifunctional electrocatalytic activities for oxidation of ascorbic acid (AA) and reduction of nitrite (NO2−).219
